5. Setup and Installation
Follow these steps to replace the rear drive wheels on your Toro lawn mower. Refer to your mower's specific service manual for detailed instructions if available.
- Prepare the Mower:
- Ensure the engine is off and cool.
- Disconnect the spark plug wire to prevent accidental starting.
- Place the mower on a flat, stable surface. If tilting the mower, ensure the carburetor side is up to prevent fuel leakage.
- Remove Old Wheel:
- Locate the retaining bolt or nut securing the wheel to the axle. This is typically found in the center of the wheel.
- Using an appropriate wrench or socket, loosen and remove the bolt/nut.
- Carefully pull the old wheel off the axle. Note the position of any washers or spacers for reinstallation.
- Inspect Axle and Components:
- Clean any debris from the axle and surrounding area.
- Inspect the axle for damage or excessive wear.
- Ensure any existing spacers or washers are clean and in good condition.
- Install New Wheel:
- Align the new Toro 98-7135 wheel with the axle. Ensure the gear side of the wheel faces inward towards the mower deck.
- Slide the wheel onto the axle, making sure any spacers or washers are correctly positioned.
- Reinstall the retaining bolt or nut. Tighten it securely, but do not overtighten, as this can damage the wheel or axle.
- Repeat for Second Wheel: Follow the same steps for the other rear drive wheel.
- Final Check:
- Ensure both new wheels are securely attached and spin freely.
- Reconnect the spark plug wire.
- Test the mower's drive system in a safe, open area.

6. Operating Considerations
While wheels do not have operational controls, proper usage of your lawn mower contributes to their longevity:
- Even Terrain: Operate the mower on relatively even terrain to minimize stress on the wheels and drive system.
- Avoid Obstacles: Steer clear of large rocks, roots, or other obstacles that could damage the wheels or tires.
- Proper Storage: Store the mower in a dry, protected area to prevent environmental damage to the rubber and metal components.
7. Maintenance
Regular maintenance helps extend the life of your rear drive wheels and ensures consistent performance.
- Regular Inspection: Periodically inspect the wheels for signs of wear, cracks in the rubber, or damage to the gear teeth. Check for any looseness in the wheel attachment.
- Cleaning: After each use, remove grass clippings, dirt, and debris from around the wheels and axle area. This prevents buildup that can impede movement or cause premature wear.
- Lubrication: Consult your lawn mower's manual for specific lubrication requirements for the axle and wheel bearings. If applicable, apply a small amount of appropriate grease to ensure smooth operation.
- Tire Tread: Monitor the tire tread. Worn tread can reduce traction, especially on inclines or wet grass. Replace wheels if the tread is significantly worn.
8. Troubleshooting
Address common issues with your rear drive wheels using the following guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Wheel not turning freely | Debris caught in axle/wheel, overtightened bolt, damaged bearing. | Remove debris, check bolt tightness, inspect/replace bearing if damaged. |
| Excessive wheel wobble | Loose retaining bolt, bent axle, damaged wheel hub. | Tighten bolt, inspect axle for bends, replace wheel if hub is damaged. |
| Poor traction | Worn tire tread, slippery conditions. | Replace wheels if tread is worn, avoid mowing on excessively wet or icy surfaces. |
| Grinding or unusual noise from wheel | Damaged gear, lack of lubrication, foreign object. | Inspect gear for damage, apply lubrication if needed, remove any obstructions. |
